Methods and systems for managing data

ABSTRACT

Systems and methods for managing data, such as metadata. In one exemplary method, metadata from files created by several different software applications are captured, and the captured metadata is searched. The type of information in metadata for one type of file differs from the type of information in metadata for another type of file. Other methods are described and data processing systems and machine readable media are also described.

This application is a divisional application of co-pending U.S. patentapplication Ser. No. 10/877,584, filed Jun. 25, 2004.

BACKGROUND OF THE INVENTION

Modern data processing systems, such as general purpose computersystems, allow the users of such systems to create a variety ofdifferent types of data files. For example, a typical user of a dataprocessing system may create text files with a word processing programsuch as Microsoft Word or may create an image file with an imageprocessing program such as Adobe's PhotoShop. Numerous other types offiles are capable of being created or modified, edited, and otherwiseused by one or more users for a typical data processing system. Thelarge number of the different types of files that can be created ormodified can present a challenge to a typical user who is seeking tofind a particular file which has been created.

Modern data processing systems often include a file management systemwhich allows a user to place files in various directories orsubdirectories (e.g. folders) and allows a user to give the file a name.Further, these file management systems often allow a user to find a fileby searching for the file's name, or the date of creation, or the dateof modification, or the type of file. An example of such a filemanagement system is the Finder program which operates on Macintoshcomputers from Apple Computer, Inc. of Cupertino, Calif. Another exampleof a file management system program is the Windows Explorer programwhich operates on the Windows operating system from MicrosoftCorporation of Redmond, Wash. Both the Finder program and the WindowsExplorer program include a find command which allows a user to searchfor files by various criteria including a file name or a date ofcreation or a date of modification or the type of file. However, thissearch capability searches through information which is the same foreach file, regardless of the type of file. Thus, for example, thesearchable data for a Microsoft Word file is the same as the searchabledata for an Adobe PhotoShop file, and this data typically includes thefile name, the type of file, the date of creation, the date of lastmodification, the size of the file and certain other parameters whichmay be maintained for the file by the file management system.

Certain presently existing application programs allow a user to maintaindata about a particular file. This data about a particular file may beconsidered metadata because it is data about other data. This metadatafor a particular file may include information about the author of afile, a summary of the document, and various other types of information.A program such as Microsoft Word may automatically create some of thisdata when a user creates a file and the user may add additional data oredit the data by selecting the “property sheet” from a menu selection inMicrosoft Word. The property sheets in Microsoft Word allow a user tocreate metadata for a particular file or document. However, in existingsystems, a user is not able to search for metadata across a variety ofdifferent applications using one search request from the user.Furthermore, existing systems can perform one search for data files, butthis search does not also include searching through metadata for thosefiles.

SUMMARY OF THE DESCRIPTION

Methods for managing data in a data processing system and systems formanaging data are described herein.

A method of managing data in one exemplary embodiment includes capturingmetadata from a plurality of files created by a plurality of differentsoftware applications which execute on a data processing system. Thetype of information in the metadata for the files of a first softwareapplication differs from the type of information in metadata for filesof a second software application. This captured metadata may besearched. In one embodiment, this search may occur concurrently for allof the metadata from the different files created by or used by thedifferent software applications. In one implementation of this method, asingle search interface may be provided to search all of the metadatafor all of the different files created by the different softwareapplications, thereby allowing a single search to search through all ofthe metadata for all of the files created by the different softwareapplications. Further, the single search may also search throughnon-metadata such as the indexed (or non-indexed) content of the actualdata files.

According to another aspect of the invention, an exemplary methodincludes capturing metadata from a plurality of different files createdby a plurality of different software applications and storing themetadata on a storage medium in a flat file format. Another aspectrelates to a flat file format for the metadata on the storage medium.

Another aspect of the present invention relates to various userinterfaces which may be provided by a system to allow a user to searchthrough the metadata. In one exemplary embodiment of such a userinterface, the method includes capturing metadata from a plurality offiles created by a plurality of different software applications anddisplaying a search input interface for searching through the metadata,wherein the type of information in metadata for files of a firstsoftware application differs from the type of information in metadatafor files of a second software application. Various implementations ofuser interfaces are discussed for search input and also for thepresentation (e.g. display) of search results. For example, the searchresults may be displayed in multiple different formats (e.g. list view,icon view, column view) and they may be displayed with headers or titleswhich separate the groups of matches in a search results list. Further,the displayed results may be limited to a predetermined number (or adynamically generated number) for each category so that a limitedviewing can still display multiple categories within a search resultwindow. Further, a search query can be saved as a folder which appearswithin a user configurable portion of the search results window, and aselection of the folder causes another search to be performed using thesaved search query (sometimes also referred to as search criteria). Adisplay of the search results from the saved search query can then besorted or further searched to limit the results to a subset of theoriginal matches from the saved search query. Numerous other userinterface implementations are shown and described. Another userinterface feature includes the ability to provide both a list view andanother view (e.g. icon view) for different portions (e.g. differentcategories) of a search results window.

Another aspect of the present invention relates to a softwarearchitecture for managing metadata. One exemplary embodiment of thisarchitecture includes a first plurality of application programs whichare capable of creating a plurality of different data files and ametadata management program which is coupled through programminginterfaces with the first plurality of application programs and which iscoupled to a file system storage of metadata which is captured fromfiles created by the first plurality of application programs. Normally,the type of information in metadata for files of a first applicationprogram differs from the type of information in metadata for files of asecond application program. The metadata management program is alsocoupled to other (non-metadata) sources of information about the datafiles such as an indexed database of the full text content of the datafiles and software which is capable of searching this indexed database.Search queries which are directed to the metadata may also beconcurrently directed to the non-metadata sources so that the searchresults include matches from both the metadata and the non-metadatasources, and these searches, through both metadata and non-metadatasources, may be in response to a single search query or a single searchrequest or command and these searches may be performed concurrently.

Another aspect of the inventions described herein relates to one or moreimporters which interact with new or modified files created by differentapplication programs. These one or more importers may be invoked (e.g.called) by the application programs or by an operating system component(e.g. a metadata processing software) which responds to a call from theapplication programs or from an operating system kernel. In oneparticular example, an importer is called by a metadata processingsoftware in response to a notification from an OS kernel that a new filehas been created or an existing file has been modified; in this case,the particular importer called by the metadata processing system willtypically depend upon the type of file (e.g. text file or image file orMP3 file, etc.), although one, single importer for all file types on asystem may be used regardless of the type of file. An importer willtypically specify a file path name for the extracted metadata andspecify selected data to be extracted and written into the file pathname of the file containing the extracted metadata.

Another aspect of the inventions described herein relates to performinga search through a system while receiving input from a user, where thesearch is through a plurality of data files created by differentsoftware applications on a data processing system. In an exemplarymethod of this aspect, the data processing system begins a searchthrough the plurality of data files as the user enters input and beforethe user completes the entry of the search query. Thus, a user may entera search (“quick brown fox”) and before the user has entered “fox,” thedata processing system has searched through, or begins to searchthrough, the plurality of data files created by different softwareapplications and has displayed the list of matches to the partial searchquery “quick brown” (or at least begins to display a partial list ofmatches to the partial search query “quick brown”). This search may beperformed through the plurality of data files as well as the metadatafor the plurality of data files, wherein the type of information inmetadata for files of a first software application differs from the typeof information in metadata for files of a second software application.The search results may be sorted by relevancy, and the system maydisplay first only a partial list of matches and then, in response to auser request, display all the matches. The search results may beorganized by categories (e.g. see FIGS. 8A and 8B). Selecting one of theitems in the search result may cause the display of additionalinformation, beyond what is already displayed in the original searchresults listing.

Another aspect of the inventions relates to a method of selecting agroup of items, such as a group of individual data files. In anexemplary method of this aspect, a data processing system receives aselection of a plurality of items such as data files, folders (e.g.graphical user interface representations of subdirectories), applicationprograms or a combination of one or more of these items. This selectionmay be performed by one of the many conventional ways to select aplurality of items such as (a) pointing a cursor at each itemindividually (e.g. through movement of a mouse) and indicating aselection individually by, for example, pressing and releasing a buttonsuch as a mouse's button; (b) pointing a cursor at a first item in alist and indicating a selection of the first item and pointing thecursor at a last item in a list of items and indicating a selection ofall items from the first item to the last item in the list; (c) drawinga selection rectangle by a dragging operation of the cursor, etc. Afterthe selection of the plurality of items has been received, the dataprocessing system receives a command to create a new folder and add ormove, e.g. in one operation, the selected plurality of items into thenew folder. The add operation creates the new folder (optionally with aname specified by the user as a result of a prompt or request by thesystem) and copies the selected files into the new folder, whichrepresents a new subdirectory. This add operation is in response to thesingle command which requests that a new folder be created and thatcopies of the selected items be created and stored with a path namereflecting storage within the new folder. The move operation alsocreates a new folder (optionally with a name specified by the user as aresult of a prompt or request by the system) and may merely change thepath names associated with each of the selected items, which changedpath names reflect the new file system location (within the subdirectoryof the new folder) of the selected items.

Other aspects of the present invention include various data processingsystems which perform these methods and machine readable media whichperform various methods described herein.

DETAILED DESCRIPTION

The subject invention will be described with reference to numerousdetails set forth below, and the accompanying drawings will illustratethe invention. The following description and drawings are illustrativeof the invention and are not to be construed as limiting the invention.Numerous specific details are described to provide a thoroughunderstanding of the present invention. However, in certain instances,well known or conventional details are not described in order to notunnecessarily obscure the present invention in detail.

The owners of thecopyrights, including the assignee of the present invention, herebyreserve their rights, including copyright, in these materials. Thecopyright owner has no objection to the facsimile reproduction by anyoneof the patent document or the patent disclosure, as it appears in thePatent and Trademark Office file or records, but otherwise reserves allcopyrights whatsoever.

FIG. 1 shows one example of a typical computer system which may be usedwith the present invention. Note that while FIG. 1 illustrates variouscomponents of a computer system, it is not intended to represent anyparticular architecture or manner of interconnecting the components assuch details are not germane to the present invention. It will also beappreciated that network computers and other data processing systemswhich have fewer components or perhaps more components may also be usedwith the present invention. The computer system of FIG. 1 may, forexample, be a Macintosh computer from Apple Computer, Inc.

As shown in FIG. 1, the computer system 101, which is a form of a dataprocessing system, includes a bus 102 which is coupled to amicroprocessor(s) 103 and a ROM (Read Only Memory) 107 and volatile RAM105 and a non-volatile memory 106. The microprocessor 103 may be a G3 orG4 microprocessor from Motorola, Inc. or one or more G5 microprocessorsfrom IBM. The bus 102 interconnects these various components togetherand also interconnects these components 103, 107, 105, and 106 to adisplay controller and display device 104 and to peripheral devices suchas input/output (I/O) devices which may be mice, keyboards, modems,network interfaces, printers and other devices which are well known inthe art. Typically, the input/output devices 109 are coupled to thesystem through input/output controllers 108. The volatile RAM (RandomAccess Memory) 105 is typically implemented as dynamic RAM (DRAM) whichrequires power continually in order to refresh or maintain the data inthe memory. The mass storage 106 is typically a magnetic hard drive or amagnetic optical drive or an optical drive or a DVD RAM or other typesof memory systems which maintain data (e.g. large amounts of data) evenafter power is removed from the system. Typically, the mass storage 106will also be a random access memory although this is not required. WhileFIG. 1 shows that the mass storage 106 is a local device coupleddirectly to the rest of the components in the data processing system, itwill be appreciated that the present invention may utilize anon-volatile memory which is remote from the system, such as a networkstorage device which is coupled to the data processing system through anetwork interface such as a modem or Ethernet interface. The bus 102 mayinclude one or more buses connected to each other through variousbridges, controllers and/or adapters as is well known in the art. In oneembodiment the I/O controller 108 includes a USB (Universal Serial Bus)adapter for controlling USB peripherals and an IEEE 1394 controller forIEEE 1394 compliant peripherals.

It will be apparent from this description that aspects of the presentinvention may be embodied, at least in part, in software. That is, thetechniques may be carried out in a computer system or other dataprocessing system in response to its processor, such as amicroprocessor, executing sequences of instructions contained in amemory, such as ROM 107, RAM 105, mass storage 106 or a remote storagedevice. In various embodiments, hardwired circuitry may be used incombination with software instructions to implement the presentinvention. Thus, the techniques are not limited to any specificcombination of hardware circuitry and software nor to any particularsource for the instructions executed by the data processing system. Inaddition, throughout this description, various functions and operationsare described as being performed by or caused by software code tosimplify description. However, those skilled in the art will recognizewhat is meant by such expressions is that the functions result fromexecution of the code by a processor, such as the microprocessor 103.

Capturing and Use of Metadata Across a Variety of Application Programs

FIG. 2 shows a generalized example of one embodiment of the presentinvention. In this example, captured metadata is made available to asearching facility, such as a component of the operating system whichallows concurrent searching of all metadata for all applications havingcaptured metadata (and optionally for all non-metadata of the datafiles). The method of FIG. 2 may begin in operation 201 in whichmetadata is captured from a variety of different application programs.This captured metadata is then made available in operation 203 to asearching facility, such as a file management system software forsearching. This searching facility allows, in operation 205, thesearching of metadata across all applications having captured metadata.The method also provides, in operation 207, a user interface of a searchengine and the search results which are obtained by the search engine.There are numerous possible implementations of the method of FIG. 2. Forexample, FIG. 5 shows a specific implementation of one exemplaryembodiment of the method of FIG. 2. Alternative implementations may alsobe used. For example, in an alternative implementation, the metadata maybe provided by each application program to a central source which storesthe metadata for use by searching facilities and which is managed by anoperating system component, which may be, for example, the metadataprocessing software. The user interface provided in operation 207 maytake a variety of different formats, including some of the examplesdescribed below as well as user interfaces which are conventional, priorart user interfaces. The metadata may be stored in a database which maybe any of a variety of formats including a B tree format or, asdescribed below, in a flat file format according to one embodiment ofthe invention.

The method of FIG. 2 may be implemented for programs which do not storeor provide metadata. In this circumstance, a portion of the operatingsystem provides for the capture of the metadata from the variety ofdifferent programs even though the programs have not been designed toprovide or capture metadata. For those programs which do allow a user tocreate metadata for a particular document, certain embodiments of thepresent invention may allow the exporting back of captured metadata backinto data files for applications which maintain metadata about theirdata files.

The method of FIG. 2 allows information about a variety of differentfiles created by a variety of different application programs to beaccessible by a system wide searching facility, which is similar to theway in which prior art versions of the Finder or Windows Explorer cansearch for file names, dates of creation, etc. across a variety ofdifferent application programs. Thus, the metadata for a variety ofdifferent files created by a variety of different application programscan be accessed through an extension of an operating system, and anexample of such an extension is shown in FIG. 4 as a metadata processingsoftware which interacts with other components of the system and will bedescribed further below.

FIGS. 3A and 3B show two different metadata formats for two differenttypes of data files. Note that there may be no overlap in any of thefields; in other words, no field in one type of metadata is the same asany field in the other type of metadata. Metadata format 301 may be usedfor an image file such as a JPEG image file. This metadata may includeinformation such as the image's width, the image's height, the image'scolor space, the number of bits per pixel, the ISO setting, the flashsetting, the F/stop of the camera, the brand name of the camera whichtook the image, user-added keywords and other fields, such as a fieldwhich uniquely identifies the particular file, which identification ispersistent through modifications of the file. Metadata format 331 shownin FIG. 3B may be used for a music file such as an MP3 music file. Thedata in this metadata format may include an identification of theartist, the genre of the music, the name of the album, song names in thealbum or the song name of the particular file, song play times or thesong play time of a particular song and other fields, such as apersistent file ID number which identifies the particular MP3 file fromwhich the metadata was captured. Other types of fields may also be used.The following chart shows examples of the various fields which may beused in metadata for various types of files.

One particular field which may be useful in the various metadata formatswould be a field which includes an identifier of a plug in or othersoftware element which may be used to capture metadata from a data fileand/or export metadata back to the creator application.

Various different software architectures may be used to implement thefunctions and operations described herein. The following discussionprovides one example of such an architecture, but it will be understoodthat alternative architectures may also be employed to achieve the sameor similar results. The software architecture shown in FIG. 4 is anexample which is based upon the Macintosh operating system. Thearchitecture 400 includes a metadata processing software 401 and anoperating system (OS) kernel 403 which is operatively coupled to themetadata processing software 401 for a notification mechanism which isdescribed below. The metadata processing software 401 is also coupled toother software programs such as a file system graphical user interfacesoftware 405 (which may be the Finder), an email software 407, and otherapplications 409. These applications are coupled to the metadataprocessing software 401 through client application program interface 411which provide a method for transferring data and commands between themetadata processing software 401 and the software 405, 407, and 409.These commands and data may include search parameters specified by auser as well as commands to perform searches from the user, whichparameters and commands are passed to the metadata processing software401 through the interface 411. The metadata processing software 401 isalso coupled to a collection of importers 413 which extract data fromvarious applications. In particular, in one exemplary embodiment, a textimporter is used to extract text and other information from wordprocessing or text processing files created by word processing programssuch as Microsoft Word, etc. This extracted information is the metadatafor a particular file. Other types of importers extract metadata fromother types of files, such as image files or music files. In thisparticular embodiment, a particular importer is selected based upon thetype of file which has been created and modified by an applicationprogram. For example, if the data file was created by PhotoShop, then animage importer for PhotoShop may be used to input the metadata from aPhotoShop data file into the metadata database 415 through the metadataprocessing software 401. On the other hand, if the data file is a wordprocessing document, then an importer designed to extract metadata froma word processing document is called upon to extract the metadata fromthe word processing data file and place it into the metadata database415 through the metadata processing software 401. Typically, a pluralityof different importers may be required in order to handle the pluralityof different application programs which are used in a typical computersystem. The importers 413 may optionally include a plurality ofexporters which are capable of exporting the extracted metadata forparticular types of data files back to property sheets or other datacomponents maintained by certain application programs. For example,certain application programs may maintain some metadata for each datafile created by the program, but this metadata is only a subset of themetadata extracted by an importer from this type of data file. In thisinstance, the exporter may export back additional metadata or may simplyinsert metadata into blank fields of metadata maintained by theapplication program.

The software architecture 400 also includes a file system directory 417for the metadata. This file system directory keeps track of therelationship between the data files and their metadata and keeps trackof the location of the metadata object (e.g. a metadata file whichcorresponds to the data file from which it was extracted) created byeach importer. In one exemplary embodiment, the metadata database ismaintained as a flat file format as described below, and the file systemdirectory 417 maintains this flat file format. One advantage of a flatfile format is that the data is laid out on a storage device as a stringof data without references between fields from one metadata file(corresponding to a particular data file) to another metadata file(corresponding to another data file). This arrangement of data willoften result in faster retrieval of information from the metadatadatabase 415.

The software architecture 400 of FIG. 4 also includes find by contentsoftware 419 which is operatively coupled to a database 421 whichincludes an index of files. The index of files represents at least asubset of the data files in a storage device and may include all of thedata files in a particular storage device (or several storage devices),such as the main hard drive of a computer system. The index of files maybe a conventional indexed representation of the content of eachdocument: The find by content software 419 searches for words in thatcontent by searching through the database 421 to see if a particularword exists in any of the data files which have been indexed. The findby content software functionality is available through the metadataprocessing software 401 which provides the advantage to the user thatthe user can search concurrently both the index of files in the database421 (for the content within a file) as well as the metadata for thevarious data files being searched. The software architecture shown inFIG. 4 may be used to perform the method shown in FIG. 5 or alternativearchitectures may be used to perform the method of FIG. 5.

The method of FIG. 5 may begin in operation 501 in which a notificationof a change for a file is received. This notification may come from theOS kernel 403 which notifies the metadata processing software 401 that afile has been changed. This notification may come from sniffer softwareelements which detect new or modified files and deletion of files. Thischange may be the creation of a new file or the modification of anexisting file or the deletion of an existing file. The deletion of anexisting file causes a special case of the processing method of FIG. 5and is not shown in FIG. 5. In the case of a deletion, the metadataprocessing software 401, through the use of the file system directory417, deletes the metadata file in the metadata database 415 whichcorresponds to the deleted file. The other types of operations, such asthe creation of a new file or the modification of an existing file,causes the processing to proceed from operation 501 to operation 503 inwhich the type of file which is the subject of the notification isdetermined. The file may be an Acrobat PDF file or an RTF wordprocessing file or a JPEG image file, etc. In any case, the type of thefile is determined in operation 503. This may be performed by receivingfrom the OS kernel 403 the type of file along with the notification orthe metadata processing software 401 may request an identification ofthe type of file from the file system graphical user interface software405 or similar software which maintains information about the data file,such as the creator application or parent application of the data file.It will be understood that in one exemplary embodiment, the file systemgraphical user interface software 405 is the Finder program whichoperates on the Macintosh operating system. In alternative embodiments,the file system graphical user interface system may be Windows Explorerwhich operates on Microsoft's Windows operating system. After the typeof file has been determined in operation 503, the appropriate capturesoftware (e.g. one of the importers 413) is activated for the determinedfile type. The importers may be a plug-in for the particular applicationwhich created the type of file about which notification is received inoperation 501. Once activated, the importer or capture software importsthe appropriate metadata (for the particular file type) into themetadata database, such as metadata database 415 as shown in operation507. Then in operation 509, the metadata is stored in the database. Inone exemplary embodiment, it may be stored in a flat file format. Thenin operation 511, the metadata processing software 401 receives searchparameter inputs and performs a search of the metadata database (andoptionally also causes a search of non-metadata sources such as theindex of files 421) and causes the results of the search to be displayedin a user interface. This may be performed by exchanging informationbetween one of the applications, such as the software 405 or thesoftware 407 or the other applications 409 and the metadata processingsoftware 401 through the interface 411. For example, the file systemsoftware 405 may present a graphical user interface, allowing a user toinput search parameters and allowing the user to cause a search to beperformed. This information is conveyed through the interface 411 to themetadata processing software 401 which causes a search through themetadata database 415 and also may cause a search through the database421 of the indexed files in order to search for content within each datafile which has been indexed. The results from these searches areprovided by the metadata processing software 401 to the requestingapplication which, in the example given here, was the software 405, butit will be appreciated that other components of software, such as theemail software 407, may be used to receive the search inputs and toprovide a display of the search results. Various examples of the userinterface for inputting search requests and for displaying searchresults are described herein and shown in the accompanying drawings.

It will be appreciated that the notification, if done through the OSkernel, is a global, system wide notification process such that changesto any file will cause a notification to be sent to the metadataprocessing software. It will also be appreciated that in alternativeembodiments, each application program may itself generate the necessarymetadata and provide the metadata directly to a metadata databasewithout the requirement of a notification from an operating systemkernel or from the intervention of importers, such as the importers 413.Alternatively, rather than using OS kernel notifications, an embodimentmay use software calls from each application to a metadata processingsoftware which receives these calls and then imports the metadata fromeach file in response to the call.

As noted above, the metadata database 415 may be stored in a flat fileformat in order to improve the speed of retrieval of information in mostcircumstances. The flat file format may be considered to be a non-Btree, non-hash tree format in which data is not attempted to beorganized but is rather stored as a stream of data. Each metadata objector metadata file will itself contain fields, such as the fields shown inthe examples of FIGS. 3A and 3B. However, there will typically be norelationship or reference or pointer from one field in one metadata fileto the corresponding field (or another field) in the next metadata fileor in another metadata file of the same file type. FIG. 6 shows anexample of the layout in a flat file format of metadata. The format 601includes a plurality of metadata files for a corresponding plurality ofdata files. As shown in FIG. 6, metadata file 603 is metadata from file1 of application A and may be referred to as metadata file A1.Similarly, metadata file 605 is metadata from file 1 of application Band may be referred to as metadata file B1. Each of these metadata filestypically would include fields which are not linked to other fields andwhich do not contain references or pointers to other fields in othermetadata files. It can be seen from FIG. 6 that the metadata database ofFIG. 6 includes metadata files from a plurality of differentapplications (applications A, B, and C) and different files created byeach of those applications. Metadata files 607, 609, 611, and 617 areadditional metadata files created by applications A, B, and C as shownin FIG. 6.

A flexible query language may be used to search the metadata database inthe same way that such query languages are used to search otherdatabases. The data within each metadata file may be packed or evencompressed if desirable. As noted above, each metadata file, in certainembodiments, will include a persistent identifier which uniquelyidentifies its corresponding data file. This identifier remains the sameeven if the name of the file is changed or the file is modified. Thisallows for the persistent association between the particular data fileand its metadata.

User Interface Aspects

Various different examples of user interfaces for inputting searchparameters and for displaying search results are provided herein. Itwill be understood that some features from certain embodiments may bemixed with other embodiments such that hybrid embodiments may resultfrom these combinations. It will be appreciated that certain featuresmay be removed from each of these embodiments and still provide adequatefunctionality in many instances.

FIG. 7A shows a graphical user interface which is a window which may bedisplayed on a display device which is coupled to a data processingsystem such as a computer system. The window 701 includes a side barhaving two regions 703A, which is a user-configurable region, and 703B,which is a region which is specified by the data processing system.Further details in connection with these side bar regions may be foundin co-pending U.S. patent application Ser. No. 10/873,661 filed Jun. 21,2004, and entitled “Methods and Apparatuses for Operating a DataProcessing System,” by inventors Donald Lindsay and Bas Ording, attorneydocket number 04860.P3306. The window 701 also includes a display region705 which in this case displays the results of searches requested by theuser. The window 701 also includes a search parameter menu bar 707 whichincludes configurable pull down menus 713, 715, and 717. The window 701also includes a text entry region 709 which allows a user to enter textas part of the search query or search parameters. The button 711 may bea start search button which a user activates in order to start a searchbased upon the selected search parameters. Alternatively, the system mayperform a search as soon as it receives any search parameter inputs orsearch queries from the user rather than waiting for a command to beginthe search. The window 701 also includes a title bar 729 which may beused in conjunction with a cursor control device to move, in aconventional manner, the window around a desktop which is displayed on adisplay device. The window 701 also includes a close button 734, aminimize button 735, and a resize button 736 which may be used to closeor minimize or resize, respectively, the window. The window 701 alsoincludes a resizing control 731 which allows a user to modify the sizeof the window on a display device. The window 701 further includes aback button 732 and a forward button 733 which function in a mannerwhich is similar to the back and forward buttons on a web browser, suchas Internet Explorer or Safari. The window 701 also includes viewcontrols which include three buttons for selecting three different typesof views of the content within the display region 705. When the contentsfound in a search exceed the available display area of a display region705, scroll controls, such as scroll controls 721, 722, and 723, appearwithin the window 701. These may be used in a conventional manner, forexample, by dragging the scroll bar 721 within the scroll region 721Ausing conventional graphical user interface techniques.

The combination of text entry region 709 and the search parameter menubar allow a user to specify a search query or search parameters. Each ofthe configurable pull down menus presents a user with a list of optionsto select from when the user activates the pull down menu. As shown inFIG. 7A, the user has already made a selection from the configurablepull down menu 713 to specify the location of the search, which in thiscase specifies that the search will occur on the local disks of thecomputer systems. Configurable pull down menu 715 has also been used bythe user to specify the kind of document which is to be searched for,which in this case is an image document as indicated by the configurablepull down menu 715 which indicates “images” as the selectedconfiguration of this menu and hence the search parameter which itspecifies. The configurable pull down menu 717, as shown in FIG. 7A,represents an add search parameter pull down menu. This add searchparameter pull down menu allows the user to add additional criteria tothe search query to further limit the search results. In the embodimentshown in FIG. 7A, each of the search parameters is logically ANDed in aBoolean manner. Thus the current search parameter specified by the userin the state shown in FIG. 7A searches all local disks for all images,and the user is in the middle of the process of selecting another searchcriteria by having selected the add search criteria pull down menu 717,resulting in the display of the pull down menu 719, which has aplurality of options which may be selected by the user.

FIG. 7B shows the window 701 after the user has caused the selection ofthe time option within pull down menu 719, thereby causing the displayof a submenu 719A which includes a list of possible times which the usermay select from. Thus it appears that the user wants to limit the searchto all images on all local disks within a certain period of time whichis to be specified by making a selection within the submenu 719A.

FIG. 7C shows the window 701 on the display of a data processing systemafter the user has selected a particular option (in this case “pastweek”) from the submenu 719A. If the user accepts this selection, thenthe display shown in FIG. 7D results in which the configurable pull downmenu 718 is displayed showing that the user has selected as part of thesearch criteria files that have been created or modified in the pastweek. It can be seen from FIG. 7D that the user can change theparticular time selected from this pull down menu 718 by selectinganother time period within the pull down menu 718A shown in FIG. 7D.Note that the configurable pull down menu 717, which represents an addsearch parameter menu, has now moved to the right of the configurablepull down menu 718. The user may add further search parameters bypressing or otherwise activating the configurable pull down menu 717from the search parameter menu bar 707. If the user decides that thepast week is the proper search criteria in the time category, then theuser may release the pull down menu 718A from being displayed in avariety of different ways (e.g. the user may release the mouse buttonwhich was being depressed to keep the pull down menu 718A on thedisplay). Upon releasing or otherwise dismissing the pull down menu718A, the resulting window 701 shown in FIG. 7E then appears. There areseveral aspects of this user interface shown in FIG. 7A-7E which areworthy of being noted. The search parameters or search query isspecified within the same window as the display of the search results.This allows the user to look at a single location or window tounderstand the search parameters and how they affected the displayedsearch results, and may make it easier for a user to alter or improvethe search parameters in order to find one or more files. Theconfigurable pull down menus, such as the add search parameter pull downmenu, includes hierarchical pull down menus. An example of this is shownin FIG. 7B in which the selection of the time criteria from the pulldown menu 717 results in the display of another menu, in this case asubmenu 719A which may be selected from by the user. This allows for acompact presentation of the various search parameters while keeping theinitial complexity (e.g. without submenus being displayed) at a lowerlevel. Another useful aspect of the user interface shown in FIG. 7A-7Eis the ability to reconfigure pull down menus which have previously beenconfigured. Thus, for example, the configurable pull down menu 713currently specifies the location of the search (in this case, all localdisks), however, this may be modified by selecting the pull down regionassociated with the configurable pull down menu 713, causing the displayof a menu of options indicating alternative locations which may beselected by the user. This can also be seen in FIG. 7D in which the pastweek option has been selected by the user (as indicated by “past week”being in the search parameter menu bar 707), but a menu of options shownin the pull down menu 718A allows the user to change the selected timefrom the “past week” to some other time criteria. Another useful aspectof this user interface is the ability to continue adding various searchcriteria by using the add search criteria pull down menu 717 andselecting a new criteria.

It will also be appreciated that the various options in the pull downmenus may depend upon the fields within a particular type of metadatafile. For example, the selection of “images” to be searched may causethe various fields present in the metadata for an image type file toappear in one or more pull down menus, allowing the user to searchwithin one or more of those fields for that particular type of file.Other fields which do not apply to “images” types of files may notappear in these menus in order reduce the complexity of the menus and toprevent user confusion.

Another feature of the present invention is shown in FIGS. 7A-7E. Inparticular, the side bar region 703A, which is the user-configurableportion of the side bar, includes a representation of a folder 725 whichrepresents the search results obtained from a particular search, whichsearch results may be static or they may be dynamic in that, in certaininstances, the search can be performed again to obtain results based onthe current files in the system. The folder 725 in the example shown inFIGS. 7A-7E represents a search on a local disk for all images done onDecember 10^(th). By selecting this folder in the side bar region 703A,the user may cause the display in the display region 705 of the resultsof that search. In this way, a user may retrieve a search resultautomatically by saving the search result into the side bar region 703A.One mechanism for causing a search result or a search query to be savedinto the side bar region 703A is to select the add folder button 727which appears in the bottom portion of the window 701. By selecting thisbutton, the current search result or search query is saved as a list offiles and other objects retrieved in the current search result. In thecase where the search query is saved for later use rather than thesaving of a search result, then the current search query is saved forre-use at a later time in order to find files which match the searchquery at that later time. The user may select between these twofunctionalities (saving a search result or saving a search query) by theselection of a command which is not shown.

FIGS. 8A and 8B show another aspect of a user interface feature whichmay be used with certain embodiments of the present invention. Thewindow 801 of FIG. 8A represents a display of the search results whichmay be obtained as a result of using one of the various differentembodiments of the present invention. The search results are separatedinto categories which are separated by headers 805, 807, 809, and 811which in this case represent periods of time. This particularsegmentation with headers was selected by the user's selecting theheading “date modified” using the date modified button 803 at the top ofthe window 801. An alternative selection of the kind category byselecting the button 802 at the top of the window 801A shown in FIG. 8Bresults in a different formatting of the search results which are nowcategorized by headers which indicate the types of files which wereretrieved in the search and are separated by the headings 815, 817, 819,and 821 as shown in FIG. 8B. The use of these headings in the searchresults display allows the user to quickly scan through the searchresults in order to find the file.

FIG. 9 shows another aspect of the present invention that is illustratedas part of the window 901 shown in FIG. 9. This window includes adisplay region 905 which shows the results of the search and the windowalso includes two side bar regions 903A and 903B, where the side barregion 903A is the user-configurable portion and the side bar region903B is the system controlled portion. A folder add button 927 may beselected by the user to cause the addition of a search result or asearch query to be added to the user-configurable portion of the sidebar. The window 901 also includes conventional window controls such as atitle bar or region 929 which may be used to move the window around adisplay and view select buttons 937 and maximize, minimize and resizebuttons 934, 935, and 936 respectively. The window 901 shows aparticular manner in which the results of a text-based search may bedisplayed. A text entry region 909 is used to enter text for searching.This text may be used to search through the metadata files or theindexed files or a combination of both. The display region 905 shows theresults of a search for text and includes at least two columns, 917 and919, which provide the name of the file that was found and the basis forthe match. As shown in column 919, the basis for the match may be theauthor field or a file name or a key word or comments or other datafields contained in metadata that was searched. The column 921 shows thetext that was found which matches the search parameter typed into thetext entry field 909. Another column 911 provides additional informationwith respect to the search results. In particular, this column includesthe number of matches for each particular type of category or field aswell as the total number of matches indicated in the entry 913. Thus,for example, the total number of matches found for the comments field isonly 1, while other fields have a higher number of matches.

FIG. 10 shows certain other aspects of some embodiments of the presentinvention. Window 1001 is another search result window which includesvarious fields and menus for a user to select various search parametersor form a search query. The window 1001 includes a display region 1005which may be used to display the results of a search and auser-configurable side bar portion 1003A and a system specified side barportion 1003B. In addition, the window 1001 includes conventionalscrolling controls such as controls 1021 and 1022 and 1021A. The windowfurther includes conventional controls such as a title bar 1029 whichmay be used to move the window and view control buttons 1037 andmaximize, minimize, and resize buttons 1034, 1035, and 1036. A startsearch button 1015 is near a text entry region 1009. A first searchparameter menu bar 1007 is displayed adjacent to a second searchparameter bar 1011. The first search parameter search bar 1007 allows auser to specify the location for a particular search while two menu pulldown controls in the second search parameter menu bar 1011 allow theuser to specify the type of file using the pull down menu 1012 and thetime the file was created or last modified using the menu 1013.

The window 1001 includes an additional feature which may be very usefulwhile analyzing a search result. A user may select individual files fromwithin the display region 1005 and associate them together as onecollection. Each file may be individually marked using a specificcommand (e.g. pressing the right button on a mouse and selecting acommand from a menu which appears on the screen, which command may be“add selection to current group”) or similar such commands. Byindividually selecting such files or by selecting a group of files atonce, the user may associate this group of files into a selected groupor a “marked” group and this association may be used to perform a commonaction on all of the files in the group (e.g. print each file or vieweach file in a viewer window or move each file to a new or existingfolder, etc.). A representation of this marked group appears as a folderin the user-configurable portion 1003A. An example of such a folder isthe folder 1020 shown in the user-configurable portion 1003A. Byselecting this folder (e.g. by positioning a cursor over the folder 1020and pressing and releasing a mouse button or by pressing another button)the user, as a result of this selection, will cause the display withinthe display region 1005 of the files which have been grouped together ormarked. Alternatively, a separate window may appear showing only theitems which have been marked or grouped. This association or groupingmay be merely temporary or it may be made permanent by retaining a listof all the files which have been grouped and by keeping a folder 1020 orother representations of the grouping within the user-configurable sidebar, such as the side bar 1003A. Certain embodiments may allow multiple,different groupings to exist at the same time, and each of thesegroupings or associations may be merely temporary (e.g. they exist onlywhile the search results window is displayed), or they may be madepermanent by retaining a list of all the files which have been groupedwithin each separate group. It will be appreciated that the files Withineach group may have been created from different applications. As notedabove, one of the groupings may be selected and then a user may select acommand which performs a common action (e.g. print or view or move ordelete) on all of the files within the selected group.

FIGS. 11A, 11B, 11C, and 11D show an alternative user interface forallowing a user to input search queries or search parameters. The userinterface shown in these figures appears within the window 1101 whichincludes a user-configurable side bar region 1103A and a systemspecified side bar region 1103B. The window 1101 also includestraditional window controls such as a window resizing control 1131 whichmay be dragged in a conventional graphical user interface manner toresize the window, and the window further includes scrolling controlssuch as controls 1121, 1122, and 1123. The scrolling control 1121 may,for example, be dragged within the scrolling region 1121A or a scrollwheel on a mouse or other input device may be used to cause scrollingwithin a display region 1105. Further, traditional window controlsinclude the title bar 1129 which may be used to move the window around adesktop which is displayed on a display device of a computer system andthe window also includes view buttons 1137 as well as close, minimize,and resize buttons 1134, 1135 and 1136. A back and forward button, suchas the back button 1132, are also provided to allow the user to moveback and forth in a manner which is similar to the back and forthcommands in a web browser. The window 1101 includes a search parametermenu bar 1111 which includes a “search by” pull down menu 1112 and a“sort by” pull down menu 1114. The “search by” pull down menu 1112allows a user to specify the particular search parameter by selectingfrom the options which appear in the pull down menu once it is activatedas shown in FIG. 11B. In particular, the pull down menu 1113 shows oneexample of a pull down menu when the “search by” pull down menu 1112 hasbeen activated. The “sort by” pull down menu 1114 allows a user tospecify how the search results are displayed within a display region1105. In the example shown in FIGS. 11A-11D a user has used the “sortby” pull down menu 1114 to select the “date viewed” criteria to sort thesearch results by. It should also be noted that the user may change thetype of view of the search results by selecting one of the three viewbuttons 1137. For example, a user may select an icon view which is thecurrently selected button among the view buttons 1137, or the user mayselect a list view or a column view.

FIG. 11B shows the result of the user's activation of a “search by” pulldown menu 1112 which causes the display of the menu 1113 which includesa plurality of options from which the user may choose to perform asearch by. It will be appreciated that there are a number of differentways for a user to activate the “search by” pull down menu 1112. One wayincludes the use of a cursor, such as a pointer on a display which iscontrolled by a cursor control device, such as a mouse. The cursor ispositioned over the region associated with the “search by” menu title(which is the portion within the search parameter menu bar 1111 whichcontains the words “search by”) and then the user indicates theselection of the menu title by pressing a button, such as a mouse'sbutton, to cause the pull down menu to appear, which in this case is themenu 1113 shown in FIG. 11B. At this point, the user may continue tomove the cursor to point to a particular option within the menu, such asthe “time” option. This may result in the display of a submenu to theleft or to the right of the menu 1113. This submenu may be similar tothe submenu 719A or to the menu 1214 shown in FIG. 12A. If the “kind”option is selected in the menu 1113, the submenu may include a genericlist of the different kinds of documents, such as images, photos,movies, text, music, PDF documents, email documents, etc. or the listmay include references to specific program names such as PhotoShop,Director, Excel, Word, etc. or it may include a combination of genericnames and specific names. FIG. 11C shows the result of the user havingselected PhotoShop type of documents from a submenu of the “kind” optionshown in menu 1113. This results in the display of the search parametermenu bar 1111A shown in FIG. 11C which includes a highlighted selection1111B which indicates that the PhotoShop type of documents will besearched for. The search parameter menu bar 1111 appears below thesearch parameter menu bar 1111A as shown in FIG. 11C. The user may thenspecify additional search parameters by again using the “search by” pulldown menu 1112 or by typing text into the text entry field 1109. Forexample, from the state of the window 1101 shown in FIG. 11C, the usermay select the “search by” pull down menu 1112 causing the display of amenu containing a plurality of options, such as the options shown withinthe menu 1113 or alternative options such as those which relate toPhotoShop documents (e.g. the various fields in the metadata forPhotoShop type of documents). A combination of such fields containedwithin metadata for PhotoShop type documents and other generic fields(e.g. time, file size, and other parameters) may appear in a menu, suchas the menu 1113 which is activated by selecting the “search by” pulldown menu. The user may then select another criteria such as the timecriteria. In this case, the window 1101 displays a new search parametermenu bar 1115 which allows a user to specify a particular time. The usermay select one of the times on the menu bar 1115 or may activate a pulldown menu by selecting the menu title “time,” which is shown as the menutitle 1116. The state of the window 1101 shown in FIG. 11D would thensearch for all PhotoShop documents created in the last 30 days or 7 daysor 2 days or today or at any time, depending on the particular timeperiod selected by the user.

FIGS. 12A, 12B, 12C and 12D show another example of a user interface forallowing the creation of search queries for searching metadata and otherdata and for displaying the results of the search performed using asearch query. The different implementation shown in FIGS. 12A-12D showsa user interface presentation in a column mode; this can be seen bynoting the selection of the column button, which is the rightmost buttonin the view buttons 1237 shown in FIG. 12A. The window 1201 has twocolumns 1211 and the display region 1205, while the window 1251 of FIG.12C has three columns which are columns 1257, 1259, and the displayregion 1255, and the window 1271 has three columns which are columns1277, 1279, and the display region 1275.

The window 1201 shown in FIGS. 12A and 12B includes a display region1205 which shows the results of a search; these results may be showndynamically as the user enters search parameters or the results may beshown only after the user has instructed the system to perform thesearch (e.g. by selecting a “perform search” command). The window 1201includes conventional window controls, such as a resizing control 1231,a scrolling control 1221, a title bar 1229 which may be used to move thewindow, a window close button, a window minimize button, and a windowresize button 1234, 1235, and 1236, respectively. The window 1201 alsoincludes a user-configurable side bar region 1203A and a systemspecified side bar region 1203B. It can be seen from FIG. 12A that abrowse mode has been selected as indicated by the highlighted “browse”icon 1203C in the system specified side bar region 1203B. The window1201 also includes a text entry region 1209, which a user may use toenter text for a search, and the window 1201 also includes view selectorbuttons 1237.

A column 1211 of window 1201 allows a user to select various searchparameters by selecting one of the options which in turn causes thedisplay of a submenu that corresponds to the selected option. In thecase of FIG. 12A, the user has selected the “kind” option 1212 and thenhas used the submenu 1214 to select the “photos” option from thesubmenu, resulting in an indicator 1213 (photos) to appear in the column1211 under the “kind” option as shown in FIG. 12A. It can also be seenthat the user has previously selected the “time” option in the column1211 and has selected from a submenu brought up when the “time” optionwas selected the “past week” search parameter. When the user hasfinished making selections of the various options and suboptions fromboth the column 1112 and any of the corresponding submenus which appear,then the display showed in FIG. 12B appears. Note that the submenus areno longer present and that the user has completed the selection of thevarious options and suboptions which specify the search parameters.Column 1211 in FIG. 12B provides feedback to the user indicating theexact nature of the search query (in this case a search for all photosdated in the past week), and the results which match the search queryare shown in the display region 1205.

FIGS. 12C and 12D show an alternative embodiment in which the submenuswhich appear on a temporary basis in the embodiment of FIGS. 12A and 12Bare replaced by an additional column which does not disappear after aselection is made. In particular, the column 1259 of the window 1251functions in the same manner as the submenu 1214 except that it remainswithin the window 1251 after a selection is made (wherein the submenu1214 is removed from the window after the user makes the selection fromthe submenu). The column 1279 of window 1271 of FIG. 12D is similar tothe column 1259. The window 1251 includes a side bar which has auser-configurable side bar region 1253A and a system defined side barregion 1253B. The system specified side bar region 1253B includes a“browse” selection region 1254 which has a clear button 1258 which theuser may select to clear the current search query. The window 1271 ofFIG. 12D provides an alternative interface for clearing the searchquery. The window 1271 also includes a user configurable side bar region1273A and a system specified side bar region 1273B, but the clearbutton, rather than being with the “search” region 1274 is at the top ofthe column 1277. The user may clear the current search parameter byselecting the button 1283 as shown in FIG. 12D.

FIG. 13A shows another embodiment of a window 1301 which displays searchresults within a display region 1302. The window 1301 may be acloseable, minimizeable, resizeable, and moveable window having aresizing control 1310, a title bar 1305 which may be used to move thewindow, a text entry region 1306 and a user configurable portion 1303,and a system specified portion 1304. The window 1301 further includesbuttons for selecting various views, including an icon view, a listview, and a column view. Currently, the list view button 1316 has beenselected, causing the display of the search results in a list viewmanner within the display region 1302. It can be seen that the text(“button”) has been entered into the text entry region 1306 and this hascaused the system to respond with the search results shown in thedisplay region 1302. The user has specified a search in every locationby selecting “everywhere” button 1317. Further, the user has searchedfor any kind of document by selecting the “kind” option from the pulldown menu 1315 and by selecting the “any” option in the pull down menu1319. The where or location slice 1307 includes a “+” button which maybe used to add further search parameters, and similarly, the slice 1308includes a “+” and a “−” button for adding or deleting searchparameters, respectively. The slice 1307 further includes a “save”button 1309 which causes the current search query to be saved in theform of a folder which is added to the user configurable portion 1303for use later. This is described further below and may be referred to asa “smart folder.” The search input user interface shown in FIGS. 13A and13B is available within, in certain embodiments, each and every windowcontrolled by a graphical user interface file management system, such asa Finder program which runs on the Macintosh or Windows Explorer whichruns on Microsoft Windows. This interface includes the text entry region1306 as well as the slices 1307 and 1308.

The window 1301 shown in FIG. 13B shows the activation of a menu byselecting the search button 1323A, causing a display of a menu havingtwo entries 1323 and 1325. Entry 1323 displays recently performedsearches so that a user may merely recall a prior search by selectingthe prior search and cause the prior search to be run again. The menuselection 1325 allows the user to clear the list of recent searches inthe menu.

FIGS. 14A, 14B, and 14C show examples of another window in a graphicaluser interface file system, such as the Finder which runs on theMacintosh operating system. These windows show the results of aparticular search and also the ability to save and use a smart folderwhich saves a prior search. The window 1401 shown in FIG. 14A includes adisplay region 1403, a user configurable region 1405, a smart folder1406, a system specified region 1407, an icon view button 1409, a listview button 1410, and a column view button 1411. The window 1401 alsoincludes a text entry region 1415 and a location slice 1416 which may beused to specify the location for the search, which slice also includes asave button 1417. Additional slices below the slice 1416 allow the userto specify further details with respect to the search, in this casespecifying types of documents which are images which were last viewedthis week. The user has set the search parameters in this manner byselecting the “kind” option from the pull down menu 1419 and byselecting the “images” type from the pull down menu 1420 and byselecting the “last viewed” option from pull down menu 1418 and byselecting “this week” from the pull down menu 1422. The user has alsoselected “everywhere” by selecting the button 1421 so that the searchwill be performed on all disks and storage devices connected to thissystem. The results are shown within the display region 1403. The usercan then save the search query by selecting the “save” button 1417 andmay name the saved search query as “this week's images” to produce thesmart folder 1406 as shown in the user configurable portion 1405. Thisallows the user to repeat this search at a later time by merelyselecting the smart folder 1406 which causes the system to perform a newsearch again, and all data which matches the search criteria will bedisplayed within the display region 1403. Thus, after several weeks, arepeating of this search by selecting the smart folder 1406 will producean entirely different list if none of the files displayed in the displayregion 1403 of FIG. 14A are viewed in the last week from the time inwhich the next search is performed by selecting the smart folder 1406.

FIG. 14B shows a way in which a user may sort or further search withinthe search results specified by a saved search, such as a smart folder.In the case of FIG. 14B, the user has selected the smart folder 1406 andhas then entered text “jpg” 1425 in the text entry region 1415. This hascaused the system to filter or further limit the search results obtainedfrom the search query saved as the smart folder 1406. Thus, PhotoShopfiles and other files such as TIF files and GIF files are excluded fromthe search results displayed within the display region 1403 of FIG. 14Bbecause the user has excluded those files by adding an additional searchcriteria specified by the text 1425 in the text entry region 1415. Itcan be seen that the “jpg” text entry is ANDed logically with the othersearch parameters to achieve the search results displayed in the displayregion 1403. It can also be seen that the user has selected the iconview by selecting the icon view button 1409. Thus, it is possible for auser to save a search query and use it later and to further limit theresults of the search query by performing a search on the results of thesearch query to further limit the search results.

FIG. 14C shows the window 1401 and shows the search results displayedwithin the display region 1403, where the results are based upon thesaved search specified by the smart folder 1406. The user has caused apull down menu 1427 to appear by selecting the pull down region 1427A.The pull down region 1427 includes several options which a user mayselect. These options include hiding the search criteria or saving thesearch (which is similar to selecting the button 1417) or showing viewoptions or opening the selected file. This allows the user, for example,to hide the search criteria, thereby causing the slice 1416 and theother search parameters to be removed from the window 1401 which is amoveable, resizeable, minimizeable, and closeable window.

FIG. 14D shows an example of a user interface which allows the user tospecify the appearance of a smart folder, such as the smart folder 1406.

FIGS. 15A, 15B, 15C, and 15D show an example of a system wide searchinput user interface and search result user interface. In one particularexemplary embodiment, these user interfaces are available on the entiresystem for all applications which run on the system and all files andmetadata, and even address book entries within an address book program,such as a personal information manager, and calendar entries within acalendar program, and emails within an email program, etc. In oneexemplary embodiment, the system begins performing the search and beginsdisplaying the results of the search as the user types text into a textentry field, such as the text entry field 1507. The search results areorganized by categories and are displayed as a short list which isintentionally abbreviated in order to present only a selected number ofthe most relevant (scored) matches or hits to the search query. The usercan ask for the display of all the hits by selecting a command, such asthe “show all” command 1509. FIG. 15A shows a portion of a displaycontrolled by a data processing system. This portion includes a menu bar1502 which has at its far end a search menu command 1505. The user canselect the search menu command by positioning a cursor, using a mouse,for example, over the search menu command 1505 and by pressing a buttonor by otherwise activating or selecting a command. This causes a displayof a text entry region 1507 into which a user can enter text. In theexample shown in FIG. 15A, which is a portion of the display, the userhas entered the text “shakeit” causing the display of a search resultregion immediately below a “show all” command region 1509 which isitself immediately below the text entry region 1507. It can be seen thatthe hits or matches are grouped into categories (“documents” and “PDFdocuments”) shown by categories 1511 and 1513 within the search resultregion 1503. FIG. 15B shows another example of a search. In this case, alarge number of hits was obtained (392 hits), only a few of which areshown in the search result region 1503. Again, the hits are organized bycategories 1511 and 1513. Each category may be restricted in terms ofthe number of items displayed within the search result region 1503 inorder to permit the display of multiple categories at the same timewithin the search result region. For example, the number of hits in thedocuments category may greatly exceed the available display space withinthe search result region 1503, but the hits for this category arelimited to a predetermined or dynamically determinable number of entrieswithin the search result region 1503 for the category 1511. Anadditional category, “top hit” is selected based on a scoring orrelevancy using techniques which are known in the art. The user mayselect the “show all” command 1509 causing the display of a window, suchas window 1601 shown in FIG. 16A. FIG. 15C shows a display of agraphical user interface of one embodiment of the invention whichincludes the menu bar 1502 and the search menu command 1505 on the menubar 1502. FIG. 15D shows another example of the search result region1503 which appeared after a search of the term “safari” was entered intothe text entry region 1507. It can be seen from the search result region1503 of FIG. 15D that the search results are again grouped intocategories. Another search result window 1520 is also shown in the userinterface of FIG. 15D. It can be seen that application programs areretrieved as part of the search results, and a user may launch any oneof these application programs by selecting it from the search resultregion, thereby causing the program to be launched.

FIGS. 16A and 16B show examples of search result windows which may becaused to appear by selecting the “show all” command 1509 in FIG. 15A or15B. Alternatively, these windows may appear as a result of the userhaving selected a “find” command or a some other command indicating thata search is desired. Moreover, the window 1601 shown in FIGS. 16A and16B may appear in response to either of the selection of a show allcommand or the selection of a find command. The window 1601 includes atext entry region 1603, a group by menu selection region 1605, a sort bymenu selection region 1607, and a where menu selection region 1609. Thegroup by selection region 1605 allows a user to specify the manner inwhich the items in the search results are grouped according to. In theexample shown in FIG. 16A, the user has selected the “kind” option fromthe group by menu selection region 1605, causing the search results tobe grouped or sorted according to the kind or type of document or file.It can be seen that the type of file includes “html” files, image files,PDF files, source code files, and other types of files as shown in FIG.16A. Each type or kind of document is separated from the other documentsby being grouped within a section and separated by headers from theother sections. Thus, headers 1611, 1613, 1615, 1617, 1619, 1621, and1623 designate each of the groups and separate one group from the othergroups. This allows a user to focus on evaluating the search resultsaccording to certain types of documents. Within each group, such as thedocument groups or the folder groups, the user has specified that theitems are to be sorted by date, because the user has selected the dateoption within the sort by menu region 1607. The user has also specifiedthat all storage locations are to be searched by selecting “everywhere”from the where menu selection region 1609. Each item in the searchresult list includes an information button 1627 which may be selected toproduce the display of additional information which may be availablefrom the system. An example of such additional information is shown inFIG. 17 in which a user has selected the information button 1627 foritem 1635, resulting in the display of an image 1636 corresponding tothe item as well as additional information 1637. Similarly, the user hasselected the information button for another item 1630 to produce thedisplay of an image of the item 1631 as well as additional information1632. The user may remove this additional information from the displayby selecting the close button 1628 which causes the display of theinformation for item 1635 to revert to the appearance for that itemshown in FIG. 16A. The user may collapse an entire group to hide theentries or search results from that group by selecting the collapsebutton 1614 shown in FIG. 16A, thereby causing the disappearance of theentries in this group as shown in FIG. 16B. The user may cause theseitems to reappear by selecting the expand button 1614A as shown in FIG.16B to thereby revert to the display of the items as shown in FIG. 16A.

The search results user interface shown in FIGS. 16A and 16B presentsonly a limited number of matches or hits within each category. In theparticular example of these figures, only the five top (most relevant ormost highly sorted) hits are displayed. This can be seen by noticing theentry at the bottom of each list within a group which specifies how manymore hits are within that group; these hits can be examined by selectingthis indicator, such as indicator 1612, which causes the display of allof the items in the documents category or kind for the search for“button” which was entered into the text entry region 1603. Furtherexamples of this behavior are described below and are shown inconjunction with FIGS. 18A and 18B. It will be appreciated that window1601 is a closeable and resizable and moveable window and includes aclose button and a resizing control 1625A.

FIGS. 18A and 18B illustrate another window 1801 which is very similarto the window 1601. The window 1801 includes a text entry region 1803, agroup by menu selection region 1805, a sort by menu selection region1807, and a where menu selection region 1809, each of which function ina manner which is similar to the regions 1605, 1607, and 1609respectively of FIG. 16A. Each item in a list view within the window1801 includes an information button 1827, allowing a user to obtainadditional information beyond that listed for each item shown in thewindow 1801. The window 1801 further includes headers 1811, 1813, 1815,1817, 1819, 1821, and 1823 which separate each group of items, groupedby the type or kind of document, and sorted within each group by date,from the other groups. A collapse button 1814 is available for each ofthe headers. The embodiment shown in FIGS. 18A and 18B shows the abilityto switch between several modes of viewing the information. For example,the user may display all of the hits within a particular group byselecting the indicator 1812 shown in FIG. 18A which results in thedisplay of all of the images files within the window 1801 within theregion 1818A. The window is scrollable, thereby allowing the user toscroll through all the images. The user can revert back to the listingof only five of the most relevant images by selecting the “show top 5”button 1832 shown in FIG. 18B. Further, the user can select between alist view or an icon view for the images portion shown in FIGS. 18A and18B. The user may select the list view by selecting the list view button1830 or may select the icon view by selecting the icon view button 1831.The list view for the images group is shown in FIG. 16A and the iconview for the images group is shown in FIGS. 18A and 18B. It can be seenthat within a single, moveable, resizable, closeable search resultwindow, that there are two different views (e.g. a list view and an iconview) which are concurrently shown within the window. For example, thePDF documents under the header 1819 are displayed in a list view whilethe images under the header 1817 are displayed in an icon view in FIGS.18A and 18B. It can also be seen from FIGS. 18A and 18B that each imageis shown with a preview which may be capable of live resizing asdescribed in a patent application entitled “Live Content Resizing” byinventors Steve Jobs, Steve Lemay, Jessica Kahn, Sarah Wilkin, DavidHyatt, Jens Alfke, Wayne Loofbourrow, and Bertrand Serlet, filed on thesame date as this application, and being assigned to the assignee of thepresent inventions described herein, and which is hereby incorporatedherein by reference.

FIG. 19A shows another example of a search result window which issimilar to the window 1601. The window 1901 shown in FIG. 19A includes atext entry region 1903 and a group by menu selection region 1905 and asort by menu selection region 1907 and a where menu selection region1908. Further, the window includes a close button 1925 and a resizingcontrol 1925A. Text has been entered into the text entry region 1903 toproduce the search results shown in the window 1901. The search resultsagain are grouped by a category selected by a user which in this case isthe people options 1906. This causes the headers 1911, 1913, 1915, and1917 to show the separation of the groups according to names of people.Within each group, the user has selected to sort by the date of theparticular file or document. The user interface shown in FIG. 19A allowsa user to specify an individual's name and to group by people to lookfor communications between two people, for example. FIG. 19B showsanother way in which a user can group a text search (“imran”) in amanner which is different from that shown in FIG. 19A. In the case ofFIG. 19B, the user has selected a flat list from the group by menuselection region 1905 and has selected “people” from the sort by menuregion 1907. The resulting display in window 1901A is without headersand thus it appears as a flat list.

FIG. 19C shows the user interface of another search result window 1930which includes a text entry region 1903 and the selection regions 1905,1907, and 1908 along with a scrolling control 1926. The results shown inthe window 1930 have been grouped by date and sorted within each groupby date. Thus, the headers 1932, 1934, 1936, 1938, and 1940 specify timeperiods such as when the document was last modified (e.g. last modifiedtoday, or yesterday, or last week). Also shown within the search resultswindow 1930 is the information button 1942 which may be selected toreveal further information, such as an icon 1945 and additionalinformation 1946 as shown for one entry under the today group. Thisadditional information may be removed by selecting the contractionbutton 1944.

FIG. 19D shows a search result window 1950 in which a search for thetext string “te” is grouped by date but the search was limited to a“home” folder as specified in the where menu selection region 1908. Timespecific headers 1952, 1954, 1956, and 1958 separate items within onegroup from the other groups as shown in FIG. 19D.

FIG. 19E shows an alternative embodiment of a search result window. Inthis embodiment, the window 1970 includes elements which are similar towindow 1901 such as the selection regions 1905, 1907, and a scrollingcontrol 1926 as well as a close button 1925 and a resizing control1925A. The search result window 1970 further includes a “when” menuselection region 1972 which allows the user to specify a searchparameter based on time in addition to the text entered into the textentry region 1903. It can be seen from the example shown in FIG. 19Ethat the user has decided to group the search results by the categoryand to sort within each group by date. This results in the headers 1973,1975, 1977, and 1979 as shown in FIG. 19E.

FIG. 20 shows an exemplary method of operating a system wide menu forinputting search queries, such as the system wide menu available byselecting the search menu command 1505 shown in FIG. 15A or 15B, or 15C.In operation 2001, the system displays a system wide menu for inputtingsearch queries. This may be the search menu command 1505. The user, inoperation 2003, inputs a search, and as the search query is beinginputted, the system begins performing and begins displaying the searchresults before the user finishes inputting the search query. This givesimmediate feedback and input to the user as the user enters thisinformation. The system is, in operation 2005, performing a searchthrough files, metadata for the files, emails within an email program,address book entries within an address book program, calendar entrieswithin a calendar program, etc. The system then, in operation 2007,displays an abbreviated (e.g. incomplete) list of hits if there are morethan a certain number of hits. An example of this abbreviated listing isshown in FIG. 15B. The listing may be sorted by relevance and segregatedinto groups such as categories or types of documents. Then in operation2009, the system receives a command from the user to display all thehits and in operation 2011 the system displays the search resultswindow, such as the window 1601 shown in FIG. 16A. This window may havethe ability to display two different types of views, such as an iconview and a list view within the same closeable, resizable, and moveablewindow. It will be appreciated that the searching, which is performed asthe user is typing and the displaying of results as the user is typingmay include the searching through the metadata files created frommetadata extracted from files created by many different types ofsoftware programs.

FIGS. 21, and 22A, 22B, 22C, and 22D will now be referred to whiledescribing another aspect of the inventions. This aspect relates to amethod of selecting a group of files, such as a group of individual datafiles. In an exemplary method of this aspect, a data processing systemreceives a selection of a plurality of items, such as data files,folders (e.g. graphical user interface representations ofsubdirectories), application programs or a combination of one or more ofthese items. This selection may be performed by one of the manyconventional ways to select a plurality of items such as (a) positioninga cursor at each item individually (e.g. through the movement of amouse) and indicating a selection individually by, for example, pressingand releasing a button, such as a mouse's button; (b) pointing a cursorat a first item in a list and indicating a selection of the first itemand pointing the cursor at a last item in a list of items and indicatinga selection of all items from the first item to the last item in thelist; (c) drawing a selection rectangle by a dragging operation of thecursor, etc. Thus operation 2101 shown in FIG. 21 receives one or moreinputs indicating a selection of a plurality of items. The system inoperation 2103 receives a command requesting both the creation of a newstorage facility (e.g. a folder) and an association of the plurality ofitems with the new storage facility. While the operation 2103 is shownfollowing operation 2101, in certain embodiments operation 2103 mayprecede operation 2101. The association of operation 2103 may be a copyor a move operation. For example, the user may select multiple items andthen command the system to move those items from their existinglocations to a new folder which is created in one operation as a resultof the move and create new folder command. In response to the commandreceived in operation 2103, the system creates a new storage facility,such as a new folder, with a predetermined directory path name or a userspecified path name and the system further associates the selectedplurality of items with the new storage facility. This association maybe either a move or a copy operation. A copy operation would typicallyinvolve making a copy of each selected item and storing the item with apath name that reflects the storage of the item within the new folderhaving a predetermined directory path name or a user specified directorypath name. A move operation, in which the items are moved into the newfolder, may merely change the path names associated with each of theselected items (rather than making a copy of the items) which changedpath names will reflect the new file system location (e.g. within thesubdirectory of the new folder) of the selected items.

FIGS. 22A-22D show one example of the method of FIG. 21. A desktop 2201on a display device is shown containing multiple windows and also anicon 2227 on the desktop. A cursor 2211 is also shown on the desktop.The windows 2203, 2205, and 2207 each contain a plurality of items shownas icons. In particular, window 2203 includes a data file represented byicon 2215 in a folder (e.g. a graphical representation of a subdirectoryin a file storage system) represented by icon 2217. The window 2205includes a program icon 2223 and a document icon 2219 and anotherdocument icon 2225 and a folder icon 2221. The window 2207 shows a listview of several files including “File B.” The user may then, using thecursor 2211 or using other conventional user interface techniques,select multiple items. This may be done with one input or more inputswhich indicate the selection of multiple items. FIG. 22B shows theresult of the user having selected icons 2215, 2217, 2223, 2225, 2227,and “File B” in window 2207. It can be seen that the cursor 2211 ispositioned adjacent to the icon 2225 at this point in the operation.Then the user, after having selected a plurality of items, may invokethe command referred to in operation 2103. An example of this is shownin FIG. 22C which represents a portion of the desktop 2101, whichportion is designated 2201A as shown in FIG. 22C. The user has caused apop up menu 2230 to appear, which pop up menu includes three options2231, 2232, and 2233. Option 2231 would allow a user to move all theselected items into the trash (e.g. delete them) while options 2232 and2233 relate to the command referred to in operation 2103 of FIG. 21. Inparticular, option 2232 is a command which is selectable by the user tocreate a new folder and, in the same operation, move the items whichhave been selected into the new folder. Option 2233 is a command whichallows the user to, in one operation, create a new folder and copy theselected items into the new folder. In the example shown in FIGS.22A-22D, the user will select option 2232, thereby causing the system tocreate a new storage facility, such as a new folder with a predetermineddirectory name (e.g. “new folder”) or alternatively, a user specifiedpath name. This result is shown in FIG. 22D in which the desktop 2201now includes a new window labeled “new folder” which represents andshows the contents of this new folder, which is also shown as the folder2253 which is a graphical user interface representation of this newfolder.

It will be appreciated that this method may employ various alternatives.For example, a window may appear after the command option 2232 or 2233has been selected, and this window asks for a name for the new folder.This window may display a default name (e.g. “new folder”) in case theuser does not enter a new name. Alternatively, the system may merelygive the new folder or new storage facility a default path name. Also,the system may merely create the new folder and move or copy the itemsinto the new folder without showing the new window as shown in FIG. 22D.

In the foregoing specification, the invention has been described withreference to specific exemplary embodiments thereof. It will be evidentthat various modifications may be made thereto without departing fromthe broader spirit and scope of the invention as set forth in thefollowing claims. The specification and drawings are, accordingly, to beregarded in an illustrative sense rather than a restrictive sense.
